Description

Technical Field

[0001] The present application relates to the field of pipeline excavation warning, and in particular to a pipeline anti-excavation warning method and system. Background Art

[0002] In order to save space on the ground, many underground pipes are buried underground in the city. These underground pipes are pre-installed with various things, such as power cables, communication cables, underground water pipes, etc., which crisscross each other.

[0003] In the related art, when excavation work is required in some places, it is usually necessary to look up the construction drawings of that year to confirm whether there are pre-buried underground pipelines in the excavation site, what the type of pre-buried underground pipelines are and the pre-buried depth, and then excavate with an excavator.

[0004] With respect to the above-mentioned related technologies, the inventors believe that when the excavator is digging, depending on the accuracy of the driver's operation, it is easy to dig beyond the digging depth, resulting in the digging of underground pipelines or underground lines inside the underground pipelines, causing serious economic losses. Summary of the invention

[0005] In order to prevent damage to underground pipelines or even breaking of underground pipelines during land excavation, thereby causing economic losses, the present application provides a pipeline anti-excavation early warning method and system.

[0006] The present application provides a pipeline anti-excavation early warning method and system using the following technical solutions:

[0007] A pipeline anti-excavation early warning method includes obtaining underground pipeline pre-buried data of a site to be excavated;

[0008] Based on the underground pipeline pre-buried data, obtaining first underground pipeline pre-buried information;

[0009] Acquiring geological information of the site to be excavated;

[0010] Based on the first underground pipeline pre-buried information and the geological information, adjusting the first underground pipeline pre-buried information to obtain second pipeline pre-buried information;

[0011] During the excavation of the site to be excavated, an anti-excavation warning for the pipeline in the site to be excavated is performed based on the second pipeline pre-buried information.

[0012] By adopting the above technical scheme, the pre-buried information of the underground pipeline is obtained according to the pre-buried data of the underground pipeline, and then the geological information of the place to be excavated is obtained. According to the geological information, it is judged whether the land to be excavated will change the pre-buried information of the pipeline. According to the first pipeline pre-buried information and the geological information, the first pipeline pre-buried information is adjusted to obtain the second pipeline pre-buried information. When excavating the land to be excavated, according to the second pipeline pre-buried information, an early warning is given to the pipeline in the land to be excavated during the excavation process, so as to prevent damage to the pipeline or damage to the line in the pipeline due to excessive excavation depth or position deviation during the excavation process, thereby preventing high economic losses.

[0013] Optionally, adjusting the first underground pipeline pre-buried information to obtain the second pipeline pre-buried information based on the first underground pipeline pre-buried information and the geological information includes:

[0014] Acquiring the geological type of the site to be excavated according to the geological information;

[0015] Acquire the position data of the pre-buried pipeline in the site to be excavated according to the first pre-buried underground pipeline information;

[0016] Based on the geological type, determining whether the position data of the pre-buried pipeline has changed;

[0017] If yes, adjust the position data of the pre-buried pipeline to obtain the second pipeline pre-buried information.

[0018] By adopting the above technical scheme, the geological type of the land to be excavated is obtained according to the geological information of the land to be excavated. The geological type is composed of local rocks and soil. The probability of ground subsidence is different for different geological types. Some weathered rock layers and soft soils are prone to land subsidence. According to the soil type of the land to be excavated, it is judged whether the position data of the pre-buried pipeline has changed. When the change occurs, the position data of the pre-buried pipeline is adjusted to obtain the second pipeline pre-buried information. When there is no change, the first pipeline pre-buried data is kept unchanged. When the land to be excavated is warned, it is judged whether the position of the pre-buried pipe has changed to avoid excavation with the previous pre-buried data when the pipeline position has changed. When there is a need, the excavation depth can be increased or decreased according to the change in the position of the underground pipeline.

[0019] Optionally, the position data includes depth data, and determining whether the position data of the pre-buried pipeline has changed includes:

[0020] Based on the geological type, determine whether the excavation site will experience ground subsidence;

[0021] If yes, obtain the settlement data of the site to be excavated, obtain the change in the depth data of the pre-buried pipeline according to the settlement data, and determine that the position data of the pre-buried pipeline has changed;

[0022] If not, it is determined that the position data of the pre-buried pipeline has not changed.

[0023] By adopting the above technical scheme, the movement of underground pipelines includes vertical movement, which is equivalent to a change in the depth of the ground. It is determined whether settlement will occur based on the geological type. When settlement occurs, the settlement data of the site to be excavated is obtained. Based on the settlement data, it is determined that the depth data of the pre-buried pipeline has changed, and it is determined that the position data of the pre-buried pipeline has changed. Based on the settlement data of the site to be excavated, it is determined whether the position of the underground pipeline has changed. The position data of the underground pipeline has changed through the settlement data of the site to be excavated, and the specific depth change of the underground pipeline can be obtained, which is convenient for adjusting the excavation height during subsequent excavation.

[0024] Optionally, determining whether ground subsidence will occur in the area to be excavated includes:

[0025] Obtain groundwater extraction data for the site to be excavated;

[0026] Determining whether the groundwater extraction data is greater than an extraction threshold;

[0027] If so, the ground subsidence occurs in the excavation site, adjusting the buried depth of the underground pipeline;

[0028] If not, the land to be excavated has no ground subsidence, and the buried depth of the underground pipeline is kept unchanged.

[0029] By adopting the above technical scheme, it is determined whether the land to be excavated will experience ground subsidence according to the geological type, and then it is determined whether the groundwater extraction data is greater than the extraction threshold based on the historical groundwater extraction data of the land to be excavated. When it is greater than the extraction threshold, it indicates that the groundwater in the land to be excavated is over-extracted, thus causing ground subsidence, which may cause the pre-buried depth of the underground pipeline to change. When the groundwater extraction data is not greater than the extraction threshold, it indicates that the groundwater usage in the land to be excavated is within the normal range, ground subsidence will not occur, and the pre-buried depth of the underground pipeline will not change.

[0030] Optionally, determining whether ground subsidence will occur in the area to be excavated includes:

[0031] Acquiring historical geological disaster data of the site to be excavated;

[0032] Based on the geological disaster data, determining whether the land to be excavated has reached a settlement level;

[0033] If so, the ground subsidence will occur in the site to be excavated, and the buried depth of the underground pipeline is adjusted;

[0034] If not, the ground settlement will not occur in the site to be excavated, and the pre-buried depth of the underground pipeline will remain unchanged.

[0035] By adopting the above technical scheme, in addition to the use of groundwater, ground subsidence also includes some geological disasters, such as minor earthquakes. According to the historical geological disaster data of the land to be excavated, the geological disaster data is the geological disasters that occurred after the pipeline was pre-buried. According to the geological disaster data, it is judged whether the land to be excavated has reached the settlement level. If it has reached it, the pre-buried depth of the underground pipeline is adjusted. If not, the pre-buried depth of the underground pipeline is kept unchanged. The situation of geological disasters is taken into account in the depth change of the underground pre-buried pipeline, thereby avoiding the impact of geological disasters on the depth change of the underground pipeline.

[0036] Optionally, the location data includes longitude and latitude data, and determining whether the location data of the pre-buried pipeline has changed includes:

[0037] Based on the geological type, determining whether ground displacement will occur in the area to be excavated;

[0038] If yes, obtain displacement data of the site to be excavated, obtain the change of longitude and latitude data of the pre-buried pipeline according to the displacement data, and determine that the position data of the pre-buried pipeline has changed;

[0039] If not, it is determined that the position data of the pre-buried pipeline has not changed.

[0040] By adopting the above technical scheme, the horizontal position of the pre-buried underground pipeline with the edge of the longitude and latitude data is moved, and it is judged whether the ground displacement will occur in the excavation site according to the geological type. If the geological type of the excavation site is such, the horizontal position movement will occur, and the displacement data is obtained. According to the displacement data, it is obtained that the longitude and latitude data of the pre-buried pipeline have changed, so as to determine that the position data of the pre-buried pipeline has changed, and the horizontal movement of the pre-buried pipeline is taken into consideration, so as to avoid the excavation of the pipeline due to the offset of the horizontal position when excavating the underground pipeline, resulting in economic losses.

[0041] Optionally, before performing the pipeline excavation prevention warning at the site to be excavated based on the second pipeline pre-buried information, the method includes:

[0042] Based on the first underground pipeline pre-buried information, obtaining the pipeline type;

[0043] Based on the pipe type, different maximum excavation depth thresholds are set.

[0044] By adopting the above technical solution, before the excavation of the pipeline is warned, the type of underground pipeline is obtained, and different pipeline types are set with a maximum excavation depth threshold. The excavation depth threshold is the maximum depth allowed for excavation. The maximum excavation depth threshold is less than the depth of the pre-buried pipeline. The maximum excavation depth is different according to the type of pipeline, so as to avoid affecting some important pipelines during excavation, and set a safety distance to protect the pre-buried pipeline.

[0045] Optionally, the setting of different maximum excavation depth thresholds based on the pipeline type includes:

[0046] Determine the importance level of the pipeline type; the importance level includes the first level, the second level and the third level;

[0047] If the importance level is the first level, excavation is prohibited;

[0048] If the importance level is the second level, the excavation depth is the first excavation depth;

[0049] If the importance level is the third level, the excavation depth is the second excavation depth;

[0050] The first excavation depth is less than the second excavation depth.

[0051] By adopting the above technical solution, the importance level of the pipeline is different according to the different types of pipelines. The importance levels are set to three levels, namely the first level, the second level and the third level. The first level is the highest protection level. When there is a first-level pipeline, excavation is prohibited here. The second level is a more important level. The excavation depth must reserve a certain protection distance to protect the pipeline. The third level is an ordinary level. The excavation depth can be less than the depth of the pre-buried pipeline. There are no other special requirements.

[0052] A pipeline anti-excavation early warning system, comprising:

[0053] The first acquisition module is used to acquire the pre-buried data of underground pipelines in the area to be excavated;

[0054] A reading module, used for acquiring first underground pipeline pre-buried information based on the underground pipeline pre-buried data;

[0055] A second acquisition module is used to acquire geological information of the site to be excavated;

[0056] an adjustment module, configured to adjust the first underground pipeline pre-buried information based on the first underground pipeline pre-buried information and the geological information to obtain second pipeline pre-buried information;

[0057] The early warning module is used to provide an early warning for preventing pipeline excavation in the site to be excavated based on the second pipeline pre-buried information during the process of excavating the site to be excavated.

[0058] By adopting the above technical solution, after the first acquisition module acquires the underground pipeline data of the site to be excavated, the reading module reads the first underground pipeline pre-buried information according to the underground pipeline data, the second module acquires the geological information of the site to be excavated, the adjustment module adjusts the first pipeline pre-buried information according to the geological information and the first underground pipeline pre-buried information to obtain the second pipeline pre-buried information, and the early warning module issues an early warning for the excavation depth of the site to be excavated according to the second pipeline pre-buried information.

[0059] In summary, the present application includes the following beneficial technical effects:

[0060] According to the underground pipeline pre-buried data, the underground pipeline pre-buried information is obtained, and then the geological information of the place to be excavated is obtained. According to the geological information, it is judged whether the land to be excavated will change the pre-buried information of the pipeline. According to the first pipeline pre-buried information and the geological information, the first pipeline pre-buried information is adjusted to obtain the second pipeline pre-buried information. When excavating the land to be excavated, according to the second pipeline pre-buried information, an early warning is given to the pipeline in the excavation land during the excavation process to prevent damage to the pipeline or damage to the line in the pipeline due to excessive excavation depth or position deviation during the excavation process, thereby preventing high economic losses.

[0071] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0072] The present application embodiment discloses a pipeline anti-excavation early warning method, referring to Figure 1 ,include:

[0073] S100: Obtaining pre-buried data of underground pipelines in a site to be excavated.

[0074] The underground pipeline pre-buried data refers to data such as the pipeline depth, horizontal position, length and pipeline type when the pipeline is pre-buried underground.

[0075] S110. Acquire first underground pipeline pre-buried information based on the underground pipeline pre-buried data.

[0076] Among them, the first underground pipeline pre-buried information includes the depth data and position data of the underground pipeline. For example, the depth of a pipeline buried in the ground is 1.5 meters, and the position is 100° east longitude and 100° south latitude.

[0077] S120: Obtain geological information of the site to be excavated.

[0078] Among them, geological information includes soil composition, rock type and compressive strength of the area to be excavated.

[0079] S130: Based on the first underground pipeline pre-buried information and the geological information, adjust the first underground pipeline pre-buried information to obtain the second underground pipeline pre-buried information.

[0080] The second pipeline pre-buried information is to adjust the depth data and position data of the pipeline based on the first pipeline pre-buried information, and the adjustment depends on the geological information of the site to be excavated.

[0081] S140. During excavation of the site to be excavated, an anti-excavation warning for the pipeline in the site to be excavated is performed based on the second pipeline pre-buried information.

[0082] Among them, during the excavation process, in order to prevent damage to the pipeline, the maximum excavation depth is controlled according to the adjusted depth data and position data of the pre-buried underground pipeline to prevent damage to the pipeline due to the excavation depth exceeding the pre-buried depth of the underground pipeline or the deviation of the excavation position.

[0083] The implementation principle of a pipeline anti-excavation early warning police in an embodiment of the present application is as follows: based on the underground pipeline pre-buried data, the underground pipeline pre-buried information is obtained, and then the geological information of the place to be excavated is obtained, and it is judged based on the geological information whether the land to be excavated will change the pre-buried information of the pipeline, and based on the first pipeline pre-buried information and the geological information, the first pipeline pre-buried information is adjusted to obtain the second pipeline pre-buried information, and when excavating the land to be excavated, according to the second pipeline pre-buried information, an early warning is given to the pipeline in the land to be excavated during the excavation process, so as to prevent damage to the pipeline or damage to the line in the pipeline due to excessive excavation depth or deviation in position during the excavation process, thereby preventing high economic losses.

[0084] exist Figure 1 In step S130 of the illustrated embodiment, based on the first underground pipeline pre-buried information and the geological information, the first underground pipeline pre-buried information is adjusted to obtain the second pipeline pre-buried information. Figure 2 The illustrated embodiment is described in detail.

[0085] Reference Figure 2 Based on the first underground pipeline pre-buried information and the geological information, adjusting the first underground pipeline pre-buried information to obtain the second pipeline pre-buried information includes:

[0086] S200: Obtaining the geological type of the site to be excavated according to geological information.

[0087] Among them, the geological type refers to the soil type and rock type of the site to be excavated. For example, the soil in a certain place is loose and the rock is weathered, so the compressive resistance of the ground in such a place is relatively weak.

[0088] S210: Acquire location data of the pre-buried pipeline in the area to be excavated according to the first pre-buried underground pipeline information.

[0089] The location data includes the depth data and longitude and latitude data of the pre-buried pipeline. The specific location of the pipeline is determined by the longitude and latitude and depth.

[0090] S220: Based on the geological type, determine whether the location data of the pre-buried pipeline has changed.

[0091] Among them, depending on the different geological types, the ground strength in some places may not be enough, and the ground may easily sink, causing the position data of the pre-buried pipeline to change as the ground sinks, which is different from the obtained position data.

[0092] S230: If yes, adjust the position data of the pre-buried pipeline to obtain the second pipeline pre-buried information.

[0093] When the position data changes, the position data of the pre-buried pipeline is adjusted according to the depth change and the change amount of the longitude and latitude to obtain the second pipeline pre-buried information.

[0094] S240: If not, do not adjust the first pipeline pre-embedded information.

[0095] When the position data does not change, the information of the first pre-buried pipeline does not change, and the pre-buried information of the first pipeline is directly used as the pre-buried information of the second pipeline.

[0096] The implementation principle of the embodiment of the present application is to adjust the first underground pipeline pre-buried information to obtain the second underground pipeline pre-buried information based on the first underground pipeline pre-buried information and the geological information as follows: the geological type is obtained according to the geological information, the pre-buried pipeline position data is obtained according to the first underground pipeline pre-buried information, and it is determined whether the position data of the pre-buried pipeline will change according to the geological type. If it will change, the first underground pipeline pre-buried information is adjusted to obtain the second underground pipeline pre-buried information. If it will not change, the first underground pipeline pre-buried information is not adjusted, and the second underground pipeline pre-buried information is replaced by the first underground pipeline pre-buried information.

[0097] exist Figure 2 In step S220 of the illustrated embodiment, it is determined whether the position data of the pre-buried pipeline has changed. Figure 3 The illustrated embodiment is described in detail.

[0098] Reference Figure 3 , the location data includes depth data, to determine whether the location data of the buried pipeline has changed, including

[0099] S300: Based on the geological type, determine whether the site to be excavated will experience ground subsidence.

[0100] Among them, if the soil structure of the area to be excavated is loose, the rock structure is weathered, or the strength of the rock type is low, in this case, the ground's bearing capacity or compressive resistance is weak, and ground subsidence is likely to occur.

[0101] S310: If yes, obtain settlement data of the site to be excavated, obtain a change in depth data of the pre-buried pipeline based on the settlement data, and determine that the position data of the pre-buried pipeline has changed.

[0102] The settlement data is the vertical offset of the pre-buried pipe relative to the previous position. As long as the settlement data is not 0, it means that the pre-buried pipe has moved in the vertical direction. Therefore, the depth data of the pre-buried pipe will change, and the position data of the pre-buried pipe will change.

[0103] S320: If not, determine that the position data of the pre-buried pipeline has not changed.

[0104] Among them, when the geological type of the excavation site is good, ground subsidence will not occur, so the position data of the pre-buried pipeline will not change.

[0105] The position data of the embodiment of the present application includes depth data. The implementation principle of determining whether the position data of the pre-buried pipe has changed is as follows: determine whether ground subsidence will occur in the area to be excavated based on the geological type; if ground subsidence will occur, obtain subsidence data; and determine whether the depth data of the pre-buried pipe has changed based on the subsidence data, thereby determining that the position data of the pre-buried pipe has changed.

[0106] exist Figure 3 In step S300 of the illustrated embodiment, whether the ground to be excavated will experience ground subsidence is determined based on the geological type. Figure 4 The illustrated embodiment is described in detail.

[0107] Reference Figure 4 , to determine whether the excavation site will experience ground subsidence, including:

[0108] S400: Obtain groundwater extraction data of the site to be excavated.

[0109] Among them, the groundwater extraction data is the amount of groundwater used in the area to be excavated. The amount of groundwater in each place is limited. Large-scale extraction of groundwater will cause the gaps caused by the drop in water levels to be unable to recover in a short period of time, and the ability to withstand pressure will be weakened, causing the ground to sink.

[0110] S410: Determine whether the groundwater extraction data is greater than the extraction threshold.

[0111] The extraction threshold is the maximum amount of exploitable groundwater allowed to maintain the stability of the ground structure.

[0112] S420. If ground subsidence occurs in the area to be excavated, adjust the pre-buried depth of the underground pipeline.

[0113] Among them, when the groundwater extraction data is greater than the extraction threshold, the geological structure is unstable due to excessive groundwater extraction. For example, the exploitable groundwater reserves in a certain place are 10,000 cubic meters, the extraction threshold is 5,000 cubic meters, and the extraction data is 6,000 cubic meters. 6,000>5,000, and the groundwater extraction data is greater than the extraction threshold. Depending on the amount of water extracted, the height of the ground subsidence is also different. According to the statistics of historical ground subsidence data, when the extraction amount is greater than the extraction threshold, the ground sinks by 0.5 meters.

[0114] S430. If no, and there is no ground subsidence in the excavation site, the buried depth of the underground pipeline shall remain unchanged.

[0115] Among them, when the groundwater extraction volume is less than the extraction threshold, it will not affect the geological compressive resistance and will not cause ground subsidence. For example, the exploitable groundwater reserves in a certain place are 10,000 cubic meters, the extraction threshold is 5,000 cubic meters, and the extraction data is 4,000 cubic meters. 4,000>5,000, and the groundwater extraction data is less than the extraction threshold.

[0116] The implementation principle of the embodiment of the present application for judging whether ground subsidence will occur in the land to be excavated is as follows: based on the groundwater extraction data of the land to be excavated, it is judged whether the groundwater extraction data is greater than the extraction threshold. If the groundwater extraction data is greater than the extraction threshold, the land to be excavated will experience subsidence, and the pre-buried depth of the underground pipeline will be adjusted. If the groundwater extraction data is less than the extraction threshold, the land to be excavated will not experience ground subsidence, and the pre-buried depth of the underground pipeline will remain unchanged.

[0117] exist Figure 3 In step S300 of the illustrated embodiment, whether the ground to be excavated will experience ground subsidence is determined based on the geological type. Figure 5 The illustrated embodiment is described in detail.

[0118] Reference Figure 5 , judging whether the excavation site will experience ground subsidence also includes:

[0119] S500: Obtain historical geological disaster data of the site to be excavated.

[0120] Among them, the historical geological disaster data refers to the data of natural disasters that occurred in the excavation area in the years after the pipeline was buried, such as minor earthquakes.

[0121] S510. Based on the geological disaster data, determine whether the land to be excavated has reached the settlement level.

[0122] Among them, the subsidence level refers to whether the level of the natural disaster that occurs can reach the extent of causing the ground to sink, such as an earthquake level of 4.

[0123] S520. If yes, adjust the buried depth of underground pipelines.

[0124] Among them, if the data of geological disasters reaches the subsidence level, it will cause land movement, resulting in changes in the depth of pre-buried underground pipelines, and adjusting the pre-buried depth of underground pipelines. It is usually counted between magnitude 4-6. Earthquakes above magnitude 6 will cause serious deformation to the entire surface. Without calculation, according to historical disaster statistics, when a magnitude 4-6 earthquake occurs, the ground sinks by about 0.3 meters.

[0125] S530. If not, keep the buried depth of underground pipeline unchanged.

[0126] Among them, when the geological disaster data does not reach the subsidence level, it will not cause the ground to sink, and the pre-buried depth of the underground pipeline will not change.

[0127] The implementation principle of the embodiment of the present application for judging whether ground subsidence will occur in the area to be excavated is as follows: by comparing the historical geological disaster data of the area to be excavated with the subsidence level, it is judged whether the disaster data reaches the subsidence level; if the subsidence level is reached, the pre-buried depth of the underground pipeline is adjusted; if the subsidence level is not reached, the pre-buried depth of the underground pipeline is not adjusted.

[0128] exist Figure 2 In step S220 of the illustrated embodiment, it is determined whether the location data of the pre-buried pipeline has changed based on the geological type. Figure 6 The illustrated embodiment is described in detail.

[0129] Reference Figure 6 The location data includes longitude and latitude data, and determines whether the location data of the pre-buried pipeline has changed, including:

[0130] S600: Based on the geological type, determine whether ground displacement will occur in the area to be excavated.

[0131] Among them, ground displacement refers to the horizontal movement of the ground. Usually, horizontal displacement will occur when natural disasters such as earthquakes or mudslides occur in the excavation area. According to historical natural disaster statistics, when the earthquake level is 4-6, the horizontal displacement distance is 0.2cm, and the direction depends on the direction of the seismic wave.

[0132] S610: If yes, obtain displacement data of the site to be excavated, determine that the longitude and latitude data of the pre-buried pipeline have changed according to the displacement data, and determine that the position data of the pre-buried pipeline has changed.

[0133] Among them, when the pre-buried pipeline is buried underground, the specific pre-buried position of the pipeline is confirmed by longitude and latitude. The displacement data is the movement of the ground relative to the ground before movement. The longitude and latitude data of the pre-buried pipeline after movement are obtained according to the previous longitude and latitude data and the moved longitude and latitude data. When the longitude and latitude data of the pre-buried underground pipeline changes, the position data of the pre-buried pipeline changes.

[0134] S620: If not, determine that the location data of the pre-buried pipeline has not changed.

[0135] When there is no displacement in the excavation site, the pre-buried underground pipeline will not move horizontally, and the position data of the pre-buried pipeline will not change.

[0136] The implementation principle of the embodiment of the present application for determining whether the position data of the buried pipeline has changed is as follows: according to the geological type, determine whether ground displacement will occur. When ground location data occurs, obtain location data, and obtain changes in longitude and latitude data based on the displacement data to determine that the position data of the buried pipeline has changed. If no ground displacement occurs, the position data of the buried pipeline remains unchanged.

[0137] exist Figure 1 Before step S130 of the illustrated embodiment, based on the first underground pipeline pre-buried information and the geological information, the first underground pipeline pre-buried information is adjusted to obtain the second pipeline pre-buried information. Figure 7 The illustrated embodiment is described in detail.

[0138] Reference Figure 7 , before the pipeline anti-excavation warning of the to-be-excavated site is performed based on the second pipeline pre-buried information, the method includes:

[0139] S700: Based on the first underground pipeline pre-buried information, obtain the pipeline type.

[0140] Among them, the pipeline type is the purpose of the pre-buried pipeline, such as drainage pipes, communication optical fiber threading pipes and power cable protection pipes, etc.

[0141] S710. Set different maximum excavation depth thresholds based on pipeline types.

[0142] The maximum excavation depth threshold is a maximum allowable excavation depth set according to different pipeline types, and the maximum excavation depth is less than the depth of the pre-buried pipeline.

[0143] The implementation principle of the embodiment of the present application before performing anti-excavation warning for pipelines in the area to be excavated based on the second pipeline pre-buried information is as follows: according to the underground pipeline pre-buried information, the pipeline type is obtained, and according to the different pipeline types, the maximum excavation depth threshold is set to control the excavation depth during excavation to protect the pipeline.

[0144] exist Figure 7 In step S710 of the illustrated embodiment, different maximum excavation depth thresholds are set based on the pipeline type, and the excavation depth is controlled according to the different excavation depth thresholds. Figure 7 The illustrated embodiment is described in detail.

[0145] Reference Figure 8 , based on the pipe type, set different maximum excavation depth thresholds including:

[0146] S800. Determine the importance level of the pipeline type; the importance levels include the first level, the second level, and the third level.

[0147] Among them, the importance level refers to the severity of damage caused during excavation according to the type of pipeline, such as economic losses.

[0148] S810. If the importance level is the first level, excavation is prohibited.

[0149] Among them, the first level is the most important level. Once the pre-buried pipeline is damaged, the consequences will be serious. For example, if the pre-buried pipeline that protects the military's communication optical cable is dug up, it will cause serious consequences. Therefore, excavation is prohibited when there is a first-level pipeline below.

[0150] S820: If the importance level is the second level, the excavation depth is the first excavation depth.

[0151] Among them, the second level is the more important level, such as power transmission cables. Digging up the cables may cause large-scale electrification and cause serious economic losses to some factories. Therefore, a safety distance needs to be reserved. For example, the buried depth of power cables in a certain place is 1.5 meters, and the maximum allowable excavation depth is 1.4 meters. A safety distance of 10 centimeters needs to be reserved.

[0152] S830: If the importance level is the third level, the excavation depth is the second excavation depth.

[0153] Among them, the third level is for smaller losses after digging, such as drainage pipes, and the second excavation depth can be less than the pre-buried depth.

[0154] S840: The first excavation depth is less than the second excavation depth.

[0155] The implementation principle of the embodiment of the present application for setting different maximum excavation depth thresholds based on pipeline type is as follows: according to the type of pre-buried underground pipeline, the importance level of the pipeline is judged, and different maximum excavation depths are set according to the different importance levels of the pipeline.

[0156] A pipeline anti-excavation early warning method is described in detail above. A pipeline anti-excavation early warning system based on the pipeline anti-excavation early warning method is described in detail below.

[0157] A pipeline anti-excavation early warning system, comprising:

[0158] The first acquisition module 1 is used to acquire the pre-buried data of underground pipelines in the area to be excavated;

[0159] Reading module 2, used for acquiring first underground pipeline pre-buried information based on underground pipeline pre-buried data;

[0160] The second acquisition module 3 is used to acquire geological information of the land to be excavated;

[0161] An adjustment module 4 is used to set the first underground pipeline pre-buried information based on the first underground pipeline pre-buried information and the geological information to obtain the second pipeline pre-buried information;

[0162] The early warning module 5 is used for providing an early warning for preventing pipeline excavation at the site to be excavated based on the second pipeline pre-buried information during the process of excavating the site to be excavated.

[0163] The implementation principle of a pipeline anti-excavation early warning system in an embodiment of the present application is as follows: after the first acquisition module 1 acquires the underground pipeline data of the site to be excavated, the reading module 2 reads the first underground pipeline pre-buried information according to the underground pipeline data, the second module acquires the geological information of the site to be excavated, the adjustment module 4 adjusts the first pipeline pre-buried information according to the geological information and the first underground pipeline pre-buried information to obtain the second pipeline pre-buried information, and the early warning module 5 issues an early warning on the excavation depth of the site to be excavated according to the second pipeline pre-buried information.

[0164] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
